... Both versions of RIP, RIPv1 and RIPv2, are Distance Vector Routing Protocols that use router hop counts as their metrics. They support a maximum hop count value of 15. Any router farther than 15 hops away is considered to be unreachable. The main enhancement of RIPv2 over its ancestor is the fact th ...
